Why Would You Want to Reset Your AC Unit?
You may need to reset your AC unit to protect your circuit breaker when your AC system kicks in. This often happens after a power outage and helps prevent explosions or fires.

How to Reset Your Air Conditioning System
If you are comfortable resetting your air conditioning unit, follow the steps below:
- Shut down your AC system: Locate the circuit breaker box, then flip the breaker that powers your AC unit. Also, remember to switch off the power switch that connects your AC to the outside unit.
- Locate the AC reset button: Most air conditioners come with a reset button. Many times, the buttons are red and small. If you seem not to find it, consult your guideline or user’s manual to locate it. Sometimes, the manufacturers of your AC may have all parts of your AC published online.
- Hold down the reset button: Hold it in the same position for 3-5 seconds, and then release it.
- Restore power supply to your AC: Do this by flipping on all the switches. Do not forget the breaker panel switch.
- Restore power to your AC. Flip on all the switches, including the one in your breaker panel.
Your air conditioner should be operational in the next few minutes. Ensure you set your thermostat at least 5 degrees lower than the actual room temperature.
Where Is the Reset Button on My Air Conditioner Located?
The AC reset button of most air conditioning units is often red and, therefore, easy to spot. Sometimes, it is on the condenser unit. You can press it and restart the unit if this is your situation.
If not, you may want to look for it on the exterior of the outdoor unit, especially along the bottom edge close to the ground.
However, if you don’t spot the reset button on the outside, it could be located inside the unit just behind the service panel. Before searching in the inside unit, cut off the power supply by switching off the circuit breaker.
What if you Don’t Have a Restart button on Your HVAC Unit?
Not all AC units come with reset buttons. If you have looked and you are sure that your system does not have one, follow the following steps to manually reset your unit:
- Turn off the power connection to the condenser. This is typically located in the shutoff panel next to the unit.
- Next, switch off the breaker in your circuit breaker box to cut off the power supply to the unit.
- Then disconnect the system by unplugging it from the power supply board. This ensures that your AC system is receiving no power.
- Wait for 20-30 minutes before plugging in the system.
If your systems do not work correctly after this reset process, you have dirty air filters or external power supply problems. Please call an HVAC technician to help diagnose your system in such a case.
